what is Autotransfusion unitAutotransfusion units are designed to collect and process blood lost by a patient to extract red blood cells (RBCs) for subsequent transfusion into the same patient.They are particularly intended for use in surgeries that involve a substantial volume of blood loss. Autotransfusion is a process wherein a person receives their own blood for a transfusion, instead of banked allogenic (separate-donor) blood.

Autotransfusion is most commonly used in the emergency department in trauma patients with evidence of a significant hemothorax.If the patient’s signs and symptoms display evidence of hemothorax preparation of autotransfusion should begin urgent before chest tube placement

what is the working principles of Autotransfusion unit1. Use of autotransfusion devices requires aspiration of extravascular blood from the surgical site into the collection reservoir of the unit, where it undergoes gross filtration.2. To keep the blood from clotting while in the unit, an anticoagulant (heparin) is added to the aspiration line at a rate proportional to the rate of blood collection.3. From the reservoir, the unit’s roller pump sends the blood into a centrifuge.bowl.

1. Once the bowl is full, the pump shuts off and the RBCs are spun and washed with normal saline to remove anticoagulant.2. The saline wash is monitored by an air detector.3. When a saline bag is depleted during the wash cycle, residual air in the saline bag is detected by the air detector, triggering an alarm to alert the operator to replace the bag.4. During the wash cycle, the saline flows into a waste bag, leaving the packed RBCs in the centrifuge bowl.5. The RBCs are then pumped into a holding bag for reinfusion and delivered to the patient through a microfilter.

what is the Advantages Autotransfusion unit1. Lower potassium (compared to stored blood).2. Quickly available.3. High levels of 2,3-DPG.4. May reduce the need for allogeneic red cell transfusion during certain surgeries, such as, adult elective cardiac and orthopaedic surgery.5. Normothermic.6. pH relatively normal.
